Single species population models and discrete stochastic gene frequency are two standards of mathematical biology important for the evolution populations. An agent based model is presented which reproduces these then explores where agree disagree under relaxed specifications. For growth models, attainment equilibrium on constant size misleading underlying characteristics may be nowhere close to...

A brief discussion of the main ideas behind population biology. The basic starting points in modelling populations, and common assumptions are discussed. Possible difficulties in assumptions are also mentioned. Different models are discussed as examples, each using different (progressively less) assumptions. Finally, the possible dangers in some of these assumptions is discussed.

If spacing behavior limits the breeding density of small mammals, the colonization of vacant areas by surplus animals ought to show how and when population regulation is achieved. Two 0.8-ha areas near...

The time evolution of spatial fluctuations in inhomogeneous d-dimensional biological systems is analyzed. A single species continuous growth model, in which the population disperses via diffusion and convection is considered. Time-independent environmental heterogeneities, such as a random distribution of nutrients or sunlight are modeled by quenched disorder in the growth rate. Linearization o...

A transposable element can be defined as a DNA sequence capable of moving to new sites in the genome. Such DNA sequences have been described in a wide range of organisms. The evolutionary processes affecting transposable elements can thus be divided into two categories: changes in sequence and changes in genomic location. As with other types of evolutionary change, the nature of the evolutionar...
